  • the processor, secondary memory and the cache.
  • the processor, main storage and the cache memory.

Question 2

Question
Main memory of RAM is used to...
Answer
  • store programs while they are running and the data used by these programs.
  • temporarily store programs while they are running and the files used by these programs.
  • temporarily store programs while they are running and the data used by these programs.

Question 3

Question
Cache is high speed memory in the CPU that is used to store a copy of frequently used instructions and data. It is used to...
Answer
  • improve the performance of the CPU.
  • improve the performance of RAM.
  • improve the performance of ROM.

Question 4

Question
Clock speed is measured in hertz or cycles per second. It represents...
Answer
  • how many instructions per minute the processor can execute.
  • how many instructions per second the processor can execute.
  • how many bits of data per second the processor can execute.

Question 5

Question
The fetch-execute cycle: the process by which a program is...
Answer
  • run: instructions are stored in main memory, fetched by the processor one at a time, decoded and executed.
  • run: instructions are stored in main memory, fetched by the processor, decoded and executed.
  • run: instructions are stored in main memory, fetched by the processor one at a time and executed.

Question 6

Question
Random Access Memory (RAM) is...
Answer
  • a type of memory that is read-write and volatile. Used for main memory.
  • a type of memory that is read-only and non-volatile. Used for main memory.
  • a type of memory that is write only and volatile. Used for main memory.

Question 7

Question
Read Only Memory (ROM) is...
Answer
  • volatile memory that is hard-coded at the time of manufacture. Stores the start up programs, the boot strap-loader.
  • non-volatile memory that is hard-coded at the time of manufacture. Stores the start up programs, the boot strap-loader.
  • memory that is hard-coded at the time of manufacture. Stores all programs, the boot strap-loader.

Question 8

Question
The bootstrap loader is the...
Answer
  • first program that is loaded into main memory from ROM when a computer is switched on. This will load the operating system from main memory.
  • first program that is loaded into main memory from RAM when a computer is switched on. This will load the operating system from secondary storage.
  • first program that is loaded into main memory from ROM when a computer is switched on. This will load the operating system from secondary storage.

Question 9

Question
Volatile memory describes memory that...
Answer
  • loses its contents when the power is turned off, e.g. RAM.
  • loses its contents when the power is turned off, e.g. ROM.
  • retains its contents when the power is turned off, e.g. ROM.

Question 10

Question
Non-volatile memory describes memory that...
Answer
  • doesn't lose its contents when the power is turned off, e.g. hard disk.
  • does lose its contents when the power is turned off, e.g. hard disk.
  • doesn't lose its contents when the power is turned off, e.g. RAM.

Question 11

Question
Virtual memory is...
Answer
  • part of the hard-disk that is configured to behave like an extension to main memory (ROM).
  • part of the hard-disk that is configured to behave like an extension to main memory (RAM).
  • part of the hard-disk that is configured to replace main memory (RAM).

Question 12

Question
